Sorry - I wasn't trying to be rude, but the suggestion is so far fetched that I thought it was some on-going joke because you're not the only one who's been suggesting we trade for Mason Miller and then pretends like the Padres will give him away for a couple broken bats.
Berrios is dead weight. If you offered him and his contract to every ML team and asked for a hot dog in return - all teams would laugh in your face. The only way you can get rid of him is to pay his salary, or include additional talent.
Mason Miller has 4 years of control left and is one of the very best, if not the best RPer in baseball. We'd have to sacrifice a metric f*ckton of talent to land him.
